Abstract

A push-pull prop includes inner and outer tubes reversibly fixed to each other, a threaded bar screwed into a threaded portion of a first end of the inner tube, a fixing head including a coupling portion fixable to a first end of the outer tube and a locking portion rotationally connected to the coupling portion, so the outer tube can rotate with respect to the locking portion about a rotation axis to thread the inner tube on the threaded bar. The locking portion is rotationally connected to a first connecting element at a first surface so the prop can rotate about a first tilting axis perpendicular to the rotation axis. The threaded bar is rotationally connected to a second connecting element at a second surface, so the prop can rotate about a second tilting axis perpendicular to the rotation axis and parallel to the first tilting axis.

Abstract

A push-pull prop (1) comprising: - an inner tube (2) and an outer tube (3) reversibly fixed to each other, - a threaded bar (6) at least partially screwed into a threaded portion of a first end (2a) of the inner tube (2), - a fixing head (7) comprising a coupling portion (8) either fixed or fixable to a first end (3a) of the outer tube (3) and a locking portion (9) rotationally connected to the coupling portion (8), so that the outer tube (3) can rotate with respect to the locking portion (9) about a rotation axis (R) of the outer tube (3) to screw or unscrew the inner tube (2) on the threaded bar (6). The locking portion (9) is configured to rotationally connect to a first connecting element (11) of the prop (1) at a first surface (S1) to be propped, so that the prop (1) can rotate about a first tilting axis (T1) of the prop (1) perpendicular to the rotation axis (R) of the outer tube (3). The threaded bar (6) is configured to rotationally connect to a second connecting element (12) of the prop (1) at a second surface (S2) to be propped, so that the prop (1) can rotate about a second tilting axis (T2) of the prop (1) perpendicular to the rotation axis (R) of the outer tube (3) and parallel to the first tilting axis (T1 ) of the prop (1 ). The fixing head (7) comprises: - an anti-friction sliding element (13) in the shape of a solid material ring, interposed between the coupling portion (8) and the locking portion (9), and - a retaining element (14) of the anti-friction sliding element (13) between the coupling portion (8) and the locking portion (9).
